iRobot Roomba 600 Series – Comparison Test

Here is the product description for the Saugrobotern the iRobot Roomba 600 series. It is the first time that we combine several models and a common product description presented above.

Due to the homogeneity of the 600 family but does it from our perspective sense. You can see at a glance which properties share the vacuum cleaner robot and where the differences between the models are.

We consider first of all the common features of the 600 product line, and then look at what technologies the manufacturer iRobot used in the 600 Saugrobotern.

The most important part of the cleaning system is the so-called “brush module”, is thus a system of three different brushes meant that each have different tasks for themselves.:

    • the main brush at the bottom of the robot picks up the dirt from the floor and from carpets using their bristles while they always rotates in the direction of the collection box,


    • the second brush is the same length, but slightly narrower and has held several rows of bristles rubber lips,


  • a third brush (such as a helicopter rotor with three blades) is mounted on the side of the robot and is used for the cleaning of edges and corners.

Brush system of the iRobot robotic vacuum cleaner
The figure shows the brush system of the Roomba household robot. Above the main brush is ready to bring the dirt from the floor and from the carpets.

Among the rubber lip brush counter rotating main brush and these supplements. Which

Lateral 3 Wing Brush finally ensures a thorough cleaning of corners and edges.

the interaction of these three components guarantees a particularly thorough and effective cleaning, the course without a further component, the actual vacuum cleaner , can not get along.

but how does it work? The main brush at the bottom of Roomba engages heavily in the subsoil (whether carpet or hard floor) and hurls out swept dirt or dust into the collection container. Due to the rotational direction of the rows of bristles on the back of the brush to the collection box move it to the bottom rows of bristles on the other hand move away from the collection box, come back to the ground and start there again with the cleaning.

Because not all dust on the bristles stuck and into the collection box, you have the second brush with the rubber lips placed directly in front of the main brush. And this second brush then rotates opposite to the first , so that they automatically everything this leaves something or indeed “free scoops”, but not transported with the bristles upward turn catches and throws towards first brush.

It is this division of labor between the two brushes at the bottom, which can be as thorough the cleaning system. But the whole system would rapidly clog if there is not a very powerful vacuum cleaner would participate!

This is in the form of so-called. AeroVac container supplied. Here the well-known from the 500 series Suction system has been improved by the vacuum cleaner was attached within the AeroVac container and the dirt sucked directly from the brush into the container. In this way, especially not as many pet hairs stick to the bristles, a not to be underestimated advantage especially for pet owners!

The Roomba the 600 product line are all “Virtual Wall” capability. The purpose of such a wall is simple, the robot from entering certain sensitive sections to prevent the apartment. The virtual wall consists of a small, approximately palm-sized box that emits an infrared beam, which makes the robot to peel off.

Especially in larger apartments with several rooms there for such virtual walls applications, but also in a single room, there may be areas which may only be cleaned by hand (play areas, tangling etc.).

What models of the 600 series of products are delivered directly to a virtual wall, read best in the section on the various models of the 600 product line . the figure shows a virtual wall in use. the transmitted through the virtual wall infrared beam prohibit the Roomba vacuum cleaner robot that entering a room. Analogously, even areas within a room to be declared as “restricted zone” by means of a virtual wall.

This system has been continued as a standard from the 500 product line. If you watch the Roomba in his work, it can be seen always fascinating as avoiding obstacles. Particularly in stairs it would be disastrous if such largely autonomous working device because not have a built-in fuse

All Roomba have a smart fall protection system , the so-called. “Cliff Detect ™ system” (in the 700 series improved even further). With a total of 4 mounted on the bottom front crash sensors, it is ideally protected against all risks of falling, they can safely drive around on a table it also, at the table edge he always makes time-versa.

To keep your Roomba but not prematurely “blind”, you should look for short throw each cleaning cycle a look at the sensors and this wipe with a cloth. the picture shows how the Cliff Detect system in Roomba product series. the sophisticated sensor system ensures that the robot cleaner is not “crash” on stairs or other abysses . the timely braking allow multiple, integrated in the 600 series infrared sensors.

The “Dirt Detect ™ system” is also a standard that is satisfied with all Roomba: it is installed only in different ways. Essentially it is about a sensor that detects the problem spots on the floor and this further reports on the software of the robot.

In the Roomba of product line 600 is the “dirt alarm” acoustically triggered: at the bottom there is a small metal plate can measure the reflections from thrown up particles. When this alarm is triggered, then added the operating system the robot in the so-called. SPOT cleaning mode . He then stops a moment and edit the recognized body in a spiral path until the sensor is clear.

All 600 also have a blue flashing warning display on its upper side, the so-called. “Dirt Detect lamp”.

All Roomba 600 series have on their upper side the following three buttons to control the device:

    • the Clean button : with this, the robot is started by hand.


    • the Dock button : this is the command to return to home base (the charger).


  • the SPOT button : for the robot is placed in the spot-cleaning mode.

This SPOT mode is nothing more than a hand (ie without the Dirt Detect System) triggered intensive cleaning mode. Usually one then applies it if you somewhere will selectively clean a field: one carries the Roomba in the center of this area, pressing the SPOT button and lets him then do the work.

But note: SPOT is not the same as CLEAN! The robot thus turns off when it has completely cleaned the SPOT-range, ie it returns to the charging station. Left is the Roomba 630 vacuum cleaner robot bird’s. All models in the 600 series are equipped with one mounted on the top panel. About the panel choose one of the 3 functions described above: CLEAN, DOCK or SPOT.

This technology is a feature that dominate all Roomba: when tangling in carpet tassels or wires, the device attempts to by forward and backward movement of this “trap” free . Of course, the brush rotation is completely stopped. If it fails the so acoustic signals help ship – also in German!

Ask the Roomba but please not to the test: without a certain preparation the suction surfaces is not. But that was also the classic vacuum cleaner so: Evacuate chairs on the table and the floor as free as possible.

The maintenance is limited to emptying the AeroVac box that tapping the dust filter in this box and, if need be, also removing hair remnants from the brushes. The introduction of AeroVac box with its particularly powerful vacuum cleaner that last part of the work has been greatly reduced.

Included is the way with all Roomba a special cleaning tool in the form of a provided with teeth plastic ring, which you can then simply drag on the brush.

And last not forget that your robot still “see”: blind crash sensors can lead to total failure!

All Roomba a powerful NiMH (Nickel Metal Hydride) battery with an identical power consumption: loading 28 watt active power for nearly 3 hours will be consumed, then it goes down to 3.6 watt active power. If you compare that with a conventional vacuum cleaner, so that mean for your electricity bill:

If you send the Roomba once a day on the road and leave it otherwise in the charging station, so it consumes about as much electricity as a 1,500-watt normal vacuum cleaner at weekly one hour of use (see also robotic vacuum electricity example ). This makes the Roomba clearly one of the energy-saving household appliances !

To fully charge the battery takes (as already mentioned) about 3 hours and fully charged then it runs about 2 hours.

To understand the navigation, we set the Roomba simply on its home-base in operation: we press the Clean button and go! What is happening? Our small household goods moves now as long as it goes straight, and if he touches anything or an obstacle in time recognizes (narrow chair legs recognize its distance sensors on the front less than thicker) and veers off before he goes straight again until the next obstacle comes.

If this procedure actually the entire area cleaned, which is accessible to the robot doing? Due to the seemingly haphazard around erring once you are inclined to a layman, that yes can hardly be the case well. We can, however, reassure the Roomba moves here for a science-based strategy, the so-called. Amoebae strategy that is used in all vacuum cleaning robots from iRobot.

If the Roomba to a longer Room edge – or the edge of an adjacent to the bottom piece of furniture – , it shall also correct navigational decision: he drives so long along the edge until another corner comes or the edge just stops. Then he turns and moves in a different direction. When edge cleaning can rest particularly clearly the effect of the three-wing side brush.

The sound pressure level of all Roomba is 70.6 dB (A), the robot is so definitely quieter than a conventional vacuum cleaner. For comparison: a passing in 10 m distances car causes a noise level of 60-80 dB (A).

Now consider the differences between the various models of the 600 series in detail:

The Roomba 615 is the entry model in the 600 series. It is characterized by a low price and has in addition to the product features listed above nor the following features:

  • no programming function,
  • there are no Virtual Wall nor the Leuchttum feature supports,
  • no replacement filters,
  • no remote control,
  • a cleaning tool supplied.
